Across the ends of the sill intersecting theshoulders 3 and l and eirtendingentirely through the raised portion 7 of the sill are grooves 8 comparatively'narrow, preferably having parallel.side walls,-and each having a bottom that isefiush substantially with the Y. outer, upper surface of the sill. These Other objects of the invention will appear sidewalls of these grooves are also preferably parallel with the endwalls 9 of the sill and separated therefrom by the narrow raised portions 10 formed whenthe grooves are cut through the raised section 7 of the sill. When the frame is assembled in the/window or door opening, the mortises or notches 6 will allow V the main portion of the sill to be inserted into I the opening while the horns or extensions 5 extend outwardly on each'side as usual in win- 'dow or door frame construction of this type. 1

The grooves 8,

as will be noted .fromthe drawin ypreferably lit . V v b extendentirel-y across the raised portlon of the sill so that rain orthe water from melting snow or ice accumulating ontlie sill and entering the grooves, will be directed-thereby to the outer side of the sill and there will be no possibility of moisture from such source en 3 tering the wall ofthe building or passing to the inner side'of the sillf The sill and jambs can beeasily and quickly assembled and when the frame is readyto be set, the jainbs and sill can be secured together in the usual way with the assurance that. allmoisture collecting in the joint between the jainbs and sills will-be I directed to the outside Theffo'iegoing views,-sheets.1-and 2, illustrate the applicationof the inventionto a. frame ofthecasen ent type, whereas shown in the figures, the innerface of each jamb has a a raised central portion extending down to the s1llwhenth'e sill .andqam'bs are assembled and the shouldert ontheisill extends to they edge of, the transverse grooves or dados in tlielsilll'. Consequently it is hardly practicable.

in this; construction to provide a lugor .wall

at the'lower endof thee-i anib as that wouldrem V der it diffic'ult toassemble the sill and: j ambs and, it "is undesirable in a window frame of this type to'cut away the rear'end ofthe raised portion in each Jainb so that it will clear the shoulder on the sill." Hence in' this type of frame I prefer to omit the shoulder or lug at the lower end of the amb,

Referring now to sheet 3 "of the drawing,

the sill 2 has. the usual horns 5 and raised portion 7 as described with reference .to the previous figures, butrthe rib 4 atthe inner edgeof the sill is preferablycut away to form gains't at each end and the sillis provided parallelfwith the dado's 8 and separated frameitype, and designated by reference nun1eral;l5."

end, the lower walls of the rabbets forming lugs or projections 17. The upper wall of the rabbet in each j amb is provided with a transverse groove 18 formed therein adapt-ed to re- 7 we ceive the rib 8 at. the end of the sill and a coris of sufiic ientjclepth to receive the: raised p'or--- respondinglyshaped tongue 19 is alsoformed in the upper wall of the rabbet to enter the groove or dado 8 in the sill, the dado in the of the'groove 18imay enterth'e'irahbet 8 fin the end of the jamb and be seated snugly therein when the silland j amb are assembled. When this has been done, thewall or lug 17 will bear on theiinder'surfacefof'the sills and cooperate with the interlocking tongues and grooves in the upper Wall of-the :jamb rabbet and thesurl-l face-.ofithe sill and. hold thelj ainb firmly in at the r-endsflof therib. P", the jambs and sill,

can .be convenientlyassembled by a relative lateral movementfland it islentirely practi- 1 cable .to. have the:- lug. or. shoulder formed on the lower endof each ija nb withoutinterfering with the convenient assemblage. Then too, inthis type 'offrame there is no central rib orraised portion on theinnerface of each j ainb as-will benoted. from theviews. I

As'shown in Figuresfll and 12. a blind stop l 20 is. preferably provided. on the-edge of the jamb with a recess 21 in its lower end forming a continuation of thefrabbetin thejamb and also providedwith' a depend-ing tongue 22 forminga continuation .of:the tongue 19.

of the jamb, Onloneside ofthis tongue, the 7 upper wallof the recessi-n the. blind stop has a groove 23', forming ;acontinuation of the groove 18in the upper, wall of the rabbet and groove 8 in thesilll'as shown This, form of. frame as described,. provides on the other side of theztongue22 a rabbet 24s. is formed which receives theinner wallof the' plainly in the r sill I may, however, prefer the form of sill shown in sheets 1 and 2 herewith,'wl1ere the transverse :rib on the. sill is close to the end thereof, without having the rabbet formed betweenit and the vertical end wall.. This construction is adaptedfor a frame of the 1 frameeonst-ruction it ispreferable to provide with transversegroovesor dados 8 and I may provide rabbets 8 at the ends of the sill V,

a rib or shoulder at theloweriendof the jamb to bear .on the under surface of the sill in the same manner as shown in sheet 3 of the :drawzing, ,and as particularly illustrated in'Figure,15,.' The rabbet may be formed in the end of the sillfor either the casement or sliding sash typeof frame, In some cases this rabbeted sillconstruction may be preferable. to

the singlatransverse groove construction inner to the outer side of the Slll, and a amb shown in the casement window figures of the drawing.

When the sill and ambs are assembled, the face of the blind stop will butt against the wall of the born 5 of the sill and with the construction of either form of sill and j amb, the joint between them will be substantially weatherproof and the extension of the dados in the sill through a substantial portion thereof from the inner edge, will conduct moisture outwardly away from the wall of the building and the inner portion of the window, an important consideration in window frame construction.

I'have shown the invention incorporated in a window frame of a casement and sliding sash type but it will be understood that the idea is equally applicable to the frame of a- I door where it is desirable to conduct moisture away from the walls and the interior of the building.

In various ways the details of construction 7 herein shown and described may be modified and still be within the scope of my invention. I claim as my invention: e

1. A sill having a raised portion extending lengthwise thereof and a groove or dado extending from the inner edge of the sill transversely through said raised portion, in which groove water may be conducted from the I having a recess the walls of which extend the full width of the ambto receive the end of (iii the sill and also having a tongue formed in and extending across the amb to enter sald groove.

5 2. Astill having atran'sverse groove or dado and a rabbet adjacent said groove forming a transverse rib across the sill, and a jamb having a transverse recess to receive the end of said sill, the jamb having a rib extending from the upper wall of said recess acting as a tongue to enter said transverse groove and a shoulder to engage said rabbet, thebottom. 45

wall of saidvrecess being seated against said sill. v

8. A sill having a transverse groove or dado and a rabbet adjacent said groove forming a transverse rib, and a j ambhaving a transverse recess to receive the end of said sill, the upper wall of said recess having a tongue to entersaid transverse groove and a shoulder to engage said rabbet, the bottom wall of said recess being seated against said sill, the lower wall of said recess having a lug or shoulder extending therefrom to engage the under surface of said sill and cooperate'with the interlocking members of the Vjamb and the upper surface of the sill, for the purpose specified.

In witness whereof, I have hereunto set my hand this 12 day of November, 1929.

EARL C. Sl/VANSON.
